准噶尔盆地北部生油岩有下侏罗统、上三叠统及二叠系风成城组,并已演化成熟,运移、储集、保存和圈闭条件良好。有利油气聚集区带有石南凸起、陆南凹陷、石西凹陷及伦北断褶带。
Northern Junggar Basin is a new area for oil and gas exploration.it can be classifiedas three first-order tectonic units:the Wulungu Depression,the Luliang-Sangequan Upliftand the Central Depression.The main source rocks in these units are the Sangonghe For-mation of the Lower Jurassic,the Baijiantan Formation of the Upper Triassic and theFongchengcheng Formation of the Lower Permian,and they have reached mature stage.The conditions for the migration,accumulation and preservation of hydrocarbon arefavourable in this area.The Shinan Uplift,the north part of the Lunan Depression andthe Lunbei faultedfold zone located in favourable position are four prospective oil-gas ac-cumulation zones.Traps ready for drilling recently are the Shinan-3 anticline,Shinan-2 nose,the faulted-nose structure to the north of Lu-4 well and the Yanchi anticline.
